在下面源程序包中dbconnector.PHP 提供了与MysqL的连接函数。
<?PHP
//定义数据连接变量
define ("MysqLHOST","localhost");
define ("MysqLUSER","root");
define ("MysqLPASS","root");
define ("MysqLDB","test");
function opendatabase(){
//连接数据库所在服务器
$db = MysqL_connect (MysqLHOST,MysqLUSER,MysqLPASS);
try {
if (!$db){
//若无法连接则提示错误
$exceptionstring = "Error connection to database: <br />";
$exceptionstring .= MysqL_errno().": ".MysqL_error();
throw new exception ($exceptionstring);
}
else{
//连接数据库（test）
MysqL_select_db (MysqLDB,$db);
}
return $db;
}catch (exception $e){
echo $e->getmessage();
die();
}
}
?>
